I would be interested in your observations on how the GroupLens predictions match up against the scores you get from the gnus score files. Right now, I think the nicest feature of GroupLens gnus is that I can read groups using the ',' key to take me to the next highest scored article. What I would like to figure out how to do is adjust the scoring somehow so I can expunge the articles with low predictions < 2 in rec.humor for example, and see the articles with high predictions plus I'd like to see all of the articles for which I have no prediction. The trouble is that my default score is 0. Is there any way to tell the expunger to throw out articles below the expunge threshold unless (= score default-score)?

As soon as we figure out how to calculate some confidence numbers that are meaningful. :-) So far, most of my efforts have been spent on just getting the whole BBB system stabilized (we seem to be there now). Over the next few weeks I plan on spending a lot of time working on and analyzing the algorithms. We've collected a LOT of ratings 30,000+ over the last six weeks, so I've got some good data to work with in trying to improve the current prediction algorithms, and hopefully get some confidence numbers. \Brad ---------------------------------------------------------------------------- Brad Miller | e-mail: bmiller@cs.umn.edu University of Minnesota | phone: (612) 626-8396 Department of Computer Science | www: http://www.cs.umn.edu/~bmiller EE/CS 5-244 | ---------------------------------------------------------------------------- ** Save USENET Try GroupLens: http://www.cs.umn.edu/Research/GroupLens ** ----------------------------------------------------------------------------
